120mm Wide Ball Screw Linear Actuator — Dual HGR15 Rails | Industrial-Grade
Overview
The Mechatronica 120mm Wide Ball Screw Linear Actuator is built for serious applications where strength, stability, and precision are non-negotiable.
Designed around a rigid 30x120mm aluminum extrusion and equipped with dual HGR15 linear rails and 4 high-load bearing blocks, this actuator offers the perfect foundation for CNC machines, automated gantry systems, and high-accuracy industrial motion.
If you're upgrading from hobby-grade components or starting a new machine design — this actuator delivers uncompromising performance in every stroke.
Key Features - Designed for Real-World Industrial Demands
12mm Thick Gantry & End Plates
The backbone of precision starts with strength. Our actuator is equipped with 12mm thick machined gantry and end plates, engineered to eliminate deflection and vibration under load. Whether you're dealing with static or dynamic forces, these robust plates maintain alignment even during heavy acceleration and deceleration cycles.
Compact, Integrated Coupling System
Unlike external coupling setups that push the motor away from the actuator, our coupling system is fully enclosed inside the actuator body. This minimises the footprint.
16mm Diameter Ball Screw with 10mm Pitch
At the heart of the actuator, the 16mm diameter precision-ground ball screw delivers smooth motion with minimal friction, excellent load-handling capability, and superior positional accuracy. The 10mm lead pitch strikes a perfect balance between speed and torque, making it ideal for applications where both fast travel and fine-resolution positioning are required.
Preloaded Nuts for Simplified Integration
Each actuator includes a set of 8 x M4 T-Nuts (4 per side) and 8 x M6 T-Nuts (bottom face) pre-installed inside the extrusion. This allows for fast, secure, and highly adaptable mounting of the actuator into your system without additional hardware or modifications. The combination of sizes gives you flexibility to attach your actuator to both lightweight fixtures and heavy-duty frames as well as adding Inductive Switches to it.
Motor Compatibility — NEMA23 & NEMA34
This actuator has been engineered for out-of-the-box compatibility with both NEMA23 and NEMA34 motor frames. This flexibility allows you to select the motor system that best fits your application's speed, torque, and control requirements, without needing custom adapters or rework.
Precision Gantry Plate Mounting System
The gantry plate is a true workhorse of modularity. Featuring 8 pre-tapped M6 mounting holes spaced precisely at 45mm center-to-center, it provides easy, symmetrical, and secure mounting for accessories, fixtures, or payloads. Whether you're attaching another axis, custom brackets, or end effectors, this pattern ensures consistent mechanical stability and makes iterative machine design faster and more efficient.
Dual HGR15 Rails with 4x HGH15CA Bearings
Equipped with two high-load HGR15 precision linear rails and four HGH15CA bearing blocks, this actuator is designed to handle substantial payloads while maintaining smooth, precise linear motion across its full travel range. The dual-rail configuration significantly enhances resistance to torque, bending, and side loading, making it ideal for both horizontal and vertical axis installations in multi-axis systems.
Rigid 30x120mm Aluminium Extrusion
The actuator’s body is constructed from a custom 30x120mm industrial-grade aluminium extrusion, offering outstanding strength-to-weight ratio and superior torsional resistance. This profile is designed to prevent bending or flexing over long spans, ensuring your system maintains perfect alignment even under high loads or long travel distances.
